CARDOOR-LO CKING DEVICE.

Application led January 23, 1922. Serial No. 531,197.

device wherein the latch member is pivotally supported by two arms, one of which is shorter than the other, so that the said member when ,actuatedy has a tilting movement as well as a swinging movement.

As is well known to those skilled in the art, drop bottom doors of freight cars are relatively easy to close with the exception ofthe last or final closing movement, due to the, facty that some of the coal dust or other material carried in the car will wedge in along the hinged edge of the door so that relatively great force has to be used to finally close and lock the door. v

With thel present invention, comprising a latch member which is to be supported at itsrearby a relatively short arm, and at its forward end by a relatively long arm, as the latch member is swung into position, its forward end not only engages the ledge formed on the door, but it also tips upwardly and thereby exerts great pressure on the door at the final or locking movement of the door.

Stilll other objects of the invention are to -provide a lock for drop bottom doors of railwaycars wherein a latch member capable of a swinging and tipping` movement is designed to be securely fastened to the side of the car body, the latch member of which will engage the ledge on the car door, and after the arm has been swung into its final position, a dog will be jammed in and against one of the supporting arms, there by holding the latch member in locked relation with the ledge on the door making it impossible for the door to accidentally open. I

Still. other objects of the invention are to provide a locking device that is relatively cheap to manufacture, compact in nature and easily and readily applied to the freight car. l

lVith these and other objects in view, the

invention consists in certain new and novel arrangements and combination of parts as will be hereinafter more fully described and pointed out in the claims.

ln the drawings showing a preferred embodiment of my invention Fig. 1 is a view in elevation showing a fragmentary portion of the side of a car, a drop bottom door having a ledge formed near its free edge and the locking device in its locked position, the dotted lines showing the position to which the locking device swings and tilts when the door is to be opened. Y

Fig. 2 is a sectional view taken on line 2-2 of Fig. `l.

Peferring now more particularly to the invention, a fragmentary portion l of a side of a car is shown, a bracket 2 which is secured to a center sill (not shown) to which in turn ishinged the drop bottom door 3 and across which, near its free edge and extending outwardly beyond the side thereof, is the angle iron 4.

Securely riveted to the side of the car and above the angle iron 4 is the base plate 5, which may have the bosses 6 at its corners, through which are passed rivets 7 lwhile a reinforcing strip v8 may be attached to the inner side of thecar to strengthen the car at this point. f

A further boss 9y is formed on the plate 5 near its upper edge and on which is supported an arm 10 and held by a rivet 11, it being noticed that the bottom of the plate 5 is slightly cored so that the head of the rivet 11 may lie flush with the side of the car. The arm 10 is also cored and at the bottom is provided an opening 12. Also pivoted to the plate 5, and preferably in the lower right hand corner, is a further arm 13, which will be noticed is much shorter in length than the arm 10, this arm also being provided at its lower end with an opening 14.

A latch member 15 is supported by the two aforementioned arms, the said latch member being hollow so that tl -e free ends of the two aforementioned arms may loosely lit therein, while two rivets 16 and 17 are provided which are passed through suitable openings formed in the latch member 15 and through the aforementioned openings 12 and 14 formed in the lower ends `of the arms 1() and 13.

Preferably formed integrally with the latch member 15 and at a point where one rivet passes through this member and the arm 13, is the boss 18, so that the same may be struck with a hammer or other instrument whendesired to either force the latch member inwardly or outwardly as the 0ckcasion arises.

Also pivotally mounted `at the top of the arm 13 and held by one of the rivets 7 is the dog .19 which is designed to be swung to engage with therearof the arm 10 when the said arm is in its` forward position, therebypreventing any Vmovement of this arm until'the dog is released which also may be accomplished by striking a boss 2() formed onv and near the upper end ot the dog.

To limit the forward movement of the arm 10 a stop 21 is formed integrally with the plate 5, and this stop is in a line with the inner vend of the top leg of the angle 4t as clearly shown in Fig. 1.

When the door is in its closed andlocked position the forward ends of the latch memthe front end droppingland the rear end raising, This'tipping action'is of greatest importance when Aclosing the door, asl after the front or forward endof the latch member engages the angle iro'nt, and from this point to its final` or locked position, lthe torward end ofthe latch member will raise, thus forcibly raising the door to `its final and locked position. i y,

From the foregoing it will be seen that I have provided a locking device kwherein the latch member is so mounted that vnot only does it swingfinto and out of position when operated, but furthermore, tipsk or tilts so that final pressure on the latch member will not only tend to lock the door, but force the. same upwardly. It will be seen' lthat I `have provided a locking device for drop doors that is rela tively simple, consisting of but few parts, easily operated and eflicient in service. Also, I have provided a locking device that will not only force the door to is locked position, but have provided means so that it will be impossible for the door to open unless the locking device is ,manually operated.

Many slight changes might be made in the shape of the latch member, or the relative position of the arms without in any way .departing` fromthe spirit and scope of the invention. l i

Having thus described the same, what I claim as new and desire to secure by Letters Aa base, two arms pivotally mounted on said base, one of said arms being shorter than theother, a latch member pivotally securedV to the lower ends of said arms, said latch member adaptedl to pass beneath a ledge on a car` door, and means for holding*` the latch member in its forward position.`

i 2. A locking device for railwa cars com.- prising a base, two arms pivotaly mounted on said base, one of said arms being shorter than theother, and the pivotal point of the short` arm beingbelowthat of the pivotal point of the longer arm, a latch member pivotally secured to the lower ends of said arms adapted to engage a ledge on a car door to thereby support the door and means for locking the latch member in its forward and -lockincr position.

3. A locing device for car doors comprising a base, arms pivotally mountedon said base,the` pivotal point `of one arm being lower than the pivotal point of the other arm, a latch member havin an aperture therein, the said arms extending into Said aperture and pivotally'secured'to said latch member, said latch member adapted toswing and tiltto engage a ledge formed onthe car door to'thereby lock the same and means for locking the latch member in its forward and supporting' position.
